Aw man, no. A wolf should pose a serious threat to a Lvl. 1 character. A goblin should be as dangerous as a kid trained in fighting with weapons - that is, less dangerous than your character (unless it's a mage going melee) but definitely not unable to kill you.
I do agree that wizards and sorcerers as they are now are not very balanced compared level to level to another character class: not able to really do anything at the beginning, while being potentially ridicoulously powerful at higher levels. And yes, that does mean that these classes should also in my opinion be able to defeat that goblin on level one using their speciality (spells), but: that
is in fact no fact. It's depending on the DM, depending on how warlike the characters are, depending how great a hero you imagine your lvl. 1 pawn to be etc. pp.I for one always find low levels particularly appealing because I can still more or less relate with what's going on which later just isn't possible anymore. DnD already begins losing appeal with the tank being able to stand in front and take all the blows of that grizzly bear, treant or whatnot and ends with puny humans defeating a colossal dragon. In short: When it's all about stats and strategy and nothing about comprehensible relations. I'm not asking to play real life now, I just wish a DnD round would feel like a dangerous adventure trip, not like... Well, I don't know... something that feels "distant". And being able to mosh through hordes of goblins at lvl 1 would not make the game more immersive to me.
